Twisted products: Enveloping actions and equivariant absolute neighborhood extensors
Luis Martínez, Héctor Pinedo
The classical notion of twisted product is studied in the context of partial actions, in particular, we show that the globalization of a partial action is a twisted product. In add…

A note on adjunction spaces and G-ANE's
Luis Martínez
We provide a different proof of the equivariant version of the Borsuk-Whitehead-Hanner Theorem in the category of proper G-spaces which are metrizable by a G-invariant metric.

Partial actions on quotient spaces and globalization
L. Martínez, H. Pinedo, A. Villamizar
Given a partial action of a topological group on a space , we determine properties which can be extended from to its globalization. We treat the cases when…
